Seems to be a trend with the Wii. a lot of people i know just seem to have them as ornaments now. I've said for a while that i think its about time Nintendo stepped up to the mark and gave the world an up to date console.
On the flip side of that however, they still sell really well. I do believe it is a novelty thing though.
I use mine for mario bros, resi evil, mario kart, mario galaxy and goldeneye. Also use the iplayer a lot. Like i said in another thread the whole motion/active gaming is a novelty which soon wears off. However the wii has some great games that keep it going. I think kinect will go the same way.
If i want to be active i will go for a walk/play football, when i play games i want to relax on sofa not jump about in front of tv
